Troubleshooting Information A common problem
with this printer is feeding multiple sheets of paper. The solution is the
replacement of the pickup roller assembly and paper separation pad. Cleaning may
work for the short term but will not solve this problem. You may find
inexpensive fixes but the answer is to replace these parts.
ERROR 11 - Paper Out
(MP/PC/UC/LC/EC/LE LOAD) 1. Paper
tray empty or not seated correctly. A buildup of toner on the edges of the
tray, which slides into the printer can sometimes cause problems. Take a
sharp tool, like a razor blade and scrape the buildup off these edges. 2. Sensor
Arm Stuck or Broken - check for free movement of the sensor arm. On the
LJ4/4M/4+/4M+ the sensor flag can get knocked out of place when a paper jam
occurs and the tray is pulled out abruptly. Most times this can simply be
reinstalled. If it's broken, you will need to replace the sensor flag. 3. Defective
Tray Size Sensing or Configuration - Most trays have tabs, which depress a
series of switches when installed. Verify that the tabs aren't damaged and
that the tray switches located in the printer are not damaged. You can depress
these by hand and hear them click. Occasionally the contact for the micro
switch will get bent and will have to be replaced. Also verify the
configuration through the menus on the printer. 4. Defective
Paper Control Sensor PCB - These do fail and will need to be replaced. ERROR 12 - Open or No EP Cartridge 1. Paper
path door (IIP/IIIP) or top cover open. On the IIP/IIIP this can be caused by
a defective toner cartridge, defective cooling fan, PS4 or PS5 sensors. Also
caused by the density adjusting PCA located behind the density adjusting
slide switch. This board takes the input from the two sensors and
provides info to the DC controller. If the board becomes defective, you will
receive an error 12. Easily replaced after removing the top cover and
three wiring harness connectors. If you want to attempt board level repair
try the electrolytic capacitor, C702, 10 uF 50 VDC. On the 4P/5P
printers, the top cover is open or no toner cartridge is installed. This
error can occur because of a defective interlock switch assembly. 2. On the
Laserjet 4/4+ an error 12 can indicate the top cover open or a broken tab on
the cover assembly. On rare occasions a defective paper control assembly or actuator
can cause this problem. Verify the tab on the cover is not broken. ERROR 13 - Paper Jam 1. Check the
paper and make sure it meets the paper specifications for your printer.
Tractor feed paper with the edges ripped off doesn't seem to work very well.
Extremely heavy or thick paper is also a problem. Check the HP paper
specification guide for more info. Be careful with labels, use only labels
designed to take the heat generated by the fuser assembly. Regular labels my
"ooze" adhesive as they pass through the fuser assembly and
literally gum up the works! Also check for any partially peeled labels, this
can be a disaster if they come off inside the printer. 2. Check the
paper path for toner or paper dust buildup. Look for bits of paper lodged in
the path particularly around the sensors. 4L/4P printers can have paper
stuck in the pickup area, which is accessed by removing the screw over the
oblique roller cover. 3. You may
have a worn pickup roller. Common on the LJII/III series is a worn input
pickup roller. Sometimes you can clean these and get a few more miles out of
them but when you start to get jams with a smudge on the top middle of the
page, it's time to replace both the input pickup roller assembly and the cork
paper separation pad. On the IIP/IIIP you can wipe toner/paper dust buildup
off the roller and also remove the separation pad (small cork pad) and clean
it as well. If the rollers are glazed or you see cracks, replace the roller
or assembly. Replacing the pickup roller and seperation pad on the IIP/IIIP
will quiet the chatter associated with a worn separation pad. 4. Is the
paper size correct? Is the software set for the size you're using? Is the
menu set for the size you're using? Check these items. If the software
tells the printer to expect a different size (legal, A4, COM10) than the tray
available, you will get an error. This can happen when printing a FAX
document formatted for A4 size paper. 5. You could
also have a defective or dirty exit sensor. Replace or clean as needed. 6. Make sure
the paper cassettes are installed correctly. A buildup of toner on the edges
of the tray, which slides into the printer, can sometimes cause problems.
Take a sharp tool, like a razor blade and scrape the buildup off these edges.
7. Bad paper
pickup solenoid. On the LJII/III series the rubber damper on the clutch
release solenoid can degrade and become sticky and gummy. You can remove it
and replace it with a piece of adhesive backed felt. Note: A sticky solenoid
can also be the cause of text appearing lower on each successive page. 8. Bad drive
gears. Again on the LJII/III we are starting to see more and more failures of
the gear drive assembly. A broken tooth on one gear is all it takes. Replace
this as an assembly. 9. Listen to
the motor, make sure it's operational. If not replace the motor or drive
circuit as required. 10. HP
IIP/IIIP and Apple Personal LaserWriter's that pickup the paper and then
crunch it up at the toner cartridge usually have a bad drive gear assembly.
If the paper crinkles right at the toner cartridge it is most likely the
drive gear located on the right side of the printer. If you fold down the
right side cover, you will see a white gear/clutch assembly. Replacing this
should solve your problem. You need RG1-1777, Drive Gear
Assembly. Take a look at the white gear - if it looks as if it
has twisted on the shaft that is the problem. You can remove it and rotate
the inner white gear - it should exhibit a one way clutch action and rotate
smoothly. The outer gear should rotate in one direction only with a spring
action, which limits it rotation. ERROR 14 - No EP Cartridge or No Toner Cartridges 1. No toner
cartridge or cartridge not fully seated - pull it out and install it again. On
the IIP/IIIP the connections for the high voltage are made on the left side
of the printer so you may want to favor that side as you install the
cartridge. 2. On the HP
LaserJet/LaserJet Plus (2686A/D) this can be caused by a defective cassette
micro switch, in which case you will have to repair or replace the switch. 3. On the II
and III Series printers, this error message can be caused by a faulty paper
control PCA. This is the board mounted to the DC power supply, which is in
the right front corner of the printer. Press the spring contacts and listen
for the micro switches. You should hear a definite clicking. 4. On the II
and III Series and the IIISi/4Si, make sure at least one of the two drum
sensitivity tabs are present. These are small rectangular blocks of plastic,
which contact the switches in the printer. 5. On the
4V/4MV check the toner cartridge micro switch on the High Voltage PCB -
SW501. 6. Also on
the 4V/4MV check the door open sensor (PS402) on the terminal board located
under the transfer roller. 7. Can also
be caused by a defective DC controller. Pretty rare though. ERROR 16 - Toner Low Message 1. Toner
cartridge is empty or toner in cartridge is not distributed evenly. Gently shake
the toner cartridge both from side to side and from front to back. This can
generally get you 100 or so more pages. 2. Bad or
dirty cartridge contacts. Look for the conductive contacts on the cartridge
and the corresponding contacts in the printer and make sure they are clean
and free of contaminants. 3. Defective
High Voltage power supply or on the LJ II/III the DC controller to High
Voltage power supply can be defective. Check for opens on the cable. 4. IIISi/4Si
check the door open sensor flag, PS1. Also check the toner level sensor and
the toner cartridge itself for damage. Another possibility could be caused by
a defective DC controller, which you can verify this by substituting a known
good DC controller if possible. ERROR 18 - MIO Not Ready 1. The printer
is not connected to a LAN when it's expecting to see a LAN. Terminate the
port on the printer with a BNC T and two 50 ohm termination's. 2. The MIO
card is defective or maybe just not seated correctly. Remove the card and
reseat it, try swapping with a known good card from another printer. Replace
if necessary ERROR 20 - Memory Overflow 1. A large
print job has exceeded the memory capacity of the printer. Verify that the
SIMMS or memory cards are seated. Add more memory or simplify the print job.
Remember the original HP Laserjet has only 128K of memory available while the
LJ+ has only 512K and neither one is really upgradeable. 2. On the 5P
turn the image adaptor and page protect to ON or AUTO. These can be set
within the Remote Control Panel. Press GO to resume printing. 3. On the
5L, set the Enhanced I/O to AUTO (PCL mode) and resend the print job. ERROR 21 - Print Overrun 1. The print

card. If the problem continues, remove the optional interface card and set
the printer for standard parallel interface by taking off-line and holding
down "Menu" key for 5-10 seconds. Scroll through items until
"I/O =" appears and use the +/- key to display parallel and the
enter key to select. Then put the printer back online and send a test job from
the host computer via the parallel cable. If this is successful, you have a
problem with the optional I/O card and should replace it or reset it. ERROR 50 - Service A 50 service error
can be either a temporary error or a permanent problem requiring service. Temporary Error:
Power off for 20 minutes to allow the capacitor on the DC controller to fully
discharge. If you don't allow this capacitor to discharge, you will still get
a Error 50 even if you have fixed the problem. This may clear the error
- either temporarily or permanently. If it clears the error it was most
likely caused by a low power problem i.e. low line voltage causing the
power supply circuits to drop out of regulation. Low/unstable power (low line
voltage, brownout condition). If it doesn't clear the error you may
have one of the problems listed below The HP LaserJet
II/IID/III/IIID, Apple LaserWriter II and many other Canon SX engine
based printers have two common causes of the Service Error 50, a
failure of the Triac in the AC power block assembly which requires rebuilding
or replacement of the assembly, and a failure of the 14 tooth gear on the
fuser assembly causing the roller to either become jammed or not turn at all
due to a broken tooth on the gear. Other possible causes are the halogen
heater lamp, the thermal fuse or the thermostat. The halogen heater lamp may
be burned out, it should have less than 5 ohms of resistance between the two
pins of the connector on the right end of the fuser assembly (you will need
to remove the fuser assembly from the printer to access this
connector). If it measures as an open circuit the lamp or thermal fuse
is burned out (these parts are connected in series). The error can be
reset by turning the machine off for 20 minutes, it is most likely the AC
power block. This condition will only worsen until the error 50 is
constant. If the lamp begins to heat (you can feel the roller, but be
very careful it's HOT ) its not the lamp or the thermal fuse and is
most likely the triac (can replace with NTE 5608 or an NTE 5645) failing when
current is drawn by the halogen heater lamp. Simply replacing the Triac
is not recommended, there are two resistors, R102 & R103, and a solid
state switch (SSR101) which should also be replaced. We have also seen the
capacitor designated as C153 on the upper board cause problems. This 22 uf
25VDC electrolytic capacitor can leak and cause shorts. You can often verify
the AC power block as the problem by opening the rear door of the printer and
observing the heater lamp glow when turning the printer on - a dark room is
best for this test. Another clue can be a "clicking" sound
just prior to the error 50 appearing. When replacing the
triac, you often need to replace the solid state relay and possibly two
resistors. It can be a labor intensive task requiring soldering skills
(you don't want to peel those pads!). Many times,
although not resulting in an error 50, the upper fuser roller simply becomes
worn, the Teflon coating begins peeling and a vertical line(s) can result on
the printed page. You can check for improper fusing in the area around the
line by running your fingernail across the print. It should not rub off! If
the coating on the roller is damaged, the entire assembly should be replaced.
It is not cost effective to replace only the defective part - upper roller,
single gear, etc. It's like tearing your engine apart to replace a single
piston ring. When you purchase a
remanufactured fuser assembly, be sure you know what parts have been replaced
and if OEM or after market parts have been used. Like anything else,
there are both acceptable and exceptional parts available. We also recommend
you replace the Ozone filter at this time. Check to see if you have the green
access door just in front of the upper cooling fan in the right rear corner
of the printer. If not, you have the older style filter, which requires
removal of the top cover to replace the filter. On HP LaserJet
IIP/IIIP/Apple Personal LaserWriter printers, a Service Error 50 is most
likely due to defective heater lamp. The halogen lamp burns out and can be
replaced quickly. You can check this by observing the coloring of the lamp,
it should be clear with the filament visible. To observe the lamp, you must
first remove the fuser assembly from the printer. The assembly is
located on the door of the printer and is the black felt/fuzz covered
assembly with the "Warning High Temperature" imprint. To
remove this assembly, remove the five brass colored screws. Slightly
flex the housing and lift straight up and out of the printer. On the
left end of the assembly you will see the ceramic lamp end with a white wire
connected to a terminal. Remove the screw securing the lug to the
terminal. Next remove the clip securing the lamp. On the right side of the
fuser is a set screw - look in the area of the cover latch. Loosen this
screw. You may now slide the lamp out of the fuser assembly. Do not
touch the glass portion with your fingers as finger oils will create hot
spots and cause premature failures. If the lamp is discolored it's
developed a leak at the glass to ceramic seal and the filament has oxidized
and is burned out. Occasionally, the power supply is at fault, usually on
older machines that were manufactured early in the product life cycle. A
manufacturing problem causes premature failure of the power supplies. To
identify if you have one of the suspected power supplies in you HP LJ IIP,
first check the S/N. This problem applies to S/N's below 2951JXXXXX. If your
S/N falls in the range, then look for a RED dot on the power supply in one of
two locations. You will have to remove the covers to do this. The first
location is just above the AC inlet either on the P/N label RG1-1782 or to
the left of the label. The other location is on the side of the power supply
on the P/N label. If you do not have the red dot, then this is probably a
defective power supply causing the 50 Service error. On the HP LaserJet
4/4M/4+/4M+, our experience so far has shown the halogen lamp to be
responsible for most error 50 problems. The thermal fuse and
thermostat are also possible causes of a 50 Service error. You can remove the
fuser assembly from the printer and measure the resistance of the
lamp/thermal fuse circuit - it should be less than five ohms. Measure
between the two heavy gauge pins on the fuser assembly connector. If you
measure an open circuit, the problem is most probably the lamp. Removal of
the lamp, although not difficult, requires knowing where the snaps are
located to remove the plastic covers.
If all four lights
are on, press and hold the blue panel button to display a secondary light
pattern. An error 50 is
indicated by the ready and error lights, with the blue panel button pressed. The HP LaserJet
5P/6P indicates service errors in a similar manner to the 4L/4ML except there
are 5 indicator lights. If the first four lights, top to bottom, are
lit, press and hold the GO and RESET buttons. If the paper jam light is
lit, you have a Service Error 50. Again, power down for 10-15 minutes
or more to see if the error resets. If not, you may have blown fuses on
the DC controller board or a DC controller failure, but in most cases you
will need to replace the fuser assembly. ERROR 51 - Service 1. Improperly

(Apple Personal LW series indicate this error with the two lower lights
flashing, QMS PS410 printers with the error light being lit) indicates
incorrect scanner speed and is generally the same as an error 51. This is a very
common failure on the LaserJet IIP/IIIP, Apple Personal Laserwriter, QMS
PS410 and other Canon LX engine printers. This error can begin as an
intermittent error which can be corrected by pressing Alt- continue (on HP
printers) but it's only a matter of time until you can no longer correct it
this way. Early models of
these machines had a scanner assembly, which contained a manufacturing
problem causing the scanner speed control IC to overheat and burn out. This
is sometimes indicated by the very distinct and pungent smell of a printed
circuit board burning. When the defective part is removed, the board material
under the speed control IC is usually burned. The scanner motor assembly on
this machine is buried deep in the center of the printer, and takes about
three quarters of an hour to change. We have seen this
failure on machines with either very low page counts - 2-3K pages or between
8-12K pages. Of course it can happen at any page count. On the HP
IIP you can get the page count by holding down the "ONLINE, MENU, and
ENTER" keys while turning the printer on. Then press the "FORM
FEED" key and then the "ENTER" key. You will see
"00 SMODE" in the display, then "05 WARM UP" and finally
the page count will be displayed. On the HP IIIP the page count is
given on the test page and on the Apple Personal Laserwriter it's on the
start up page (except the LS). Heat and moisture
are likely to aggravate the problem and induce failure. The replacement
parts, which are made for Canon by Toshiba, do not have the manufacturing
problem. In very rare instances, the laser diode itself will be the cause of
failure, usually resulting in an error 51. Listen to the scanner motor, it
should have a distinct "whirring" sound as the printer prepares to
print. Once the proper speed is reached, it should stabilize and the printer
should print. If you don't hear the motor at all, usually accompanied
by an error 52 indication, the scanner motor is defective. If you hear
the motor spin but not stabilize and you get an error 52 the scanner motor is
most likely defective. If you do hear the motor reach speed and then you
receive and error 51 you may have a defective laser diode although this is
fairly rare. On the LJII/III and
the Apple Laserwriter II series, this error is generally caused by
loose connectors and may be indicated by an error 51 message. Many
times the scanner motor will rev up and fail to stabilize - indicated by a
whining motor sound. A common solution
is to tighten the connectors at both the scanner assembly and the DC
controller. This is accomplished by removing the connector from its mate and
tweaking or bending in slightly on the connector tabs. When reseating the
connector, use a small flat blade screwdriver to fully seat the female
connector ends. You may also find the tie wraps on the wire harness are to
tight, pinching the wires and causing an open or short. Simply cut these
off. Occasionally, the scanner motor will fail in which case it must be
replaced. Replacement is fairly straight forward requiring removal of the
cover assembly, fiber optic cable, two connectors and four screws. We have
found it is highly beneficial to replace the wire harness assembly and fiber
optic cable when replacing the scanner since by this time you have probably
already tried tweaking the connectors. While this involves more disassembly,
our experience has shown it to be a worthwhile effort. These parts are also
available on our parts page. On the LaserJet 4
Series, an ERROR 51/52 is usually an indication of a defective scanner
assembly. You should check for loose connections first of course. ERROR 53 - Service On the HP LaserJet
